Increasing blood carbon dioxide levels decreases breathing rate?

∙ 12y ago
Carbon dioxide levels regulate breathing via the chemoreceptors in your brain, carotid arteries, and aorta. As Carbon dioxide levels go up, the pH of the cerbrospinal fluid goes down (becomes acidic) and triggers a reaction by the chemoreceptors in your brain to cause you to breath. Specifically, those receptors are located in the floor of the fourth ventricle (in your brain stem for all intents and purposes). Expelling CO2 by breathing brings your cerebrospinal fluid's pH back down to acceptable levels. The chemoreceptors in your carotid arteries and aorta respond to the partial pressures of CO2 as well as the partial pressure of oxygen. Basically, it also tells you to breath when your CO2 levels get too high. Ultimately, it looks like when you hold your breath and "run out of air", you don't actually run out of oxygen, but you accumulate too much CO2 (after all, we can make ATP without oxygen, it just makes nasty byproducts *muscles -> lactic acid* but if our pH gets too high, we don't have a real good contingency plan for fixing it quickly)

∙ 13y agoThe concentration of blood carbon dioxide regulates a person's breathing because blood pH operates within a very narrow range and a very small change can lead to death. If a person's concentration of blood carbon dioxide is high his/her blood is more acidic, and if a person's concentration of blood carbon dioxide is low his/her blood is more basic. When there is a build-up or deficiency of carbon dioxide in the blood stream, messages to the brain will force a person to respire.
This is why people breath heavier when exercising. Exercising increases the rate of cellular respiration by the muscles, resulting in an increase in the amount of carbon dioxide in the blood, which requires heavy breathing in order to decrease and be exchanged with oxygen.

∙ 14y agogas exchange occurs in the alveoli in the lungs ... every cell needs 02 a general rule is air goes in and out aka(co2 u have to blow off-or out) and blood goes round and round .. 500ml is our tidal volume u need good gas exchange to keep the blood oxygenated
The important principle to remember is that oxygen is needed by the cell and that carbon dioxide is produced as a waste product of the cell. Carbon dioxide must be expelled from the cells and the body.
The lungs serve to exchange the two gases in the blood. Oxygen enters the blood from the lungs and carbon dioxide is expelled out of the blood into the lungs. The blood serves to transport both gases. Oxygen is carried to the cells. Carbon dioxide is carried away from the cells.

What process is breathing out carbon dioxide part of?
Respiration is breathing in and absorbing oxygen, and breathing out carbon dioxide.
What would happen if you kept on breathing in carbon dioxide?
There is carbon dioxide in the atmosphere. You have been breathing it in all your life.
Breathing out carbon dioxide is an example of a life process?
an excretion is an example of breathing out Co2
What happens when breathing rate increases?
When the breathing rate increases, more oxygen is brought into the body and more carbon dioxide is removed. This helps to meet the increased demand for oxygen by the body during physical activity or moments of stress. Increased breathing rate can also help regulate the pH balance in the blood by removing excess carbon dioxide.
What causes carbon dioxide?
fossil fuels and breathing causes carbon dioxide :)
What type of process is breathing'?
respitatory, taking oxygen in...and breathing carbon dioxide out. carbon dioxide=Co2 and oxygen = O
An increase in the amount of carbon dioxide in the blood stimulates the respirayory center in the brainas a result a message is sent from the brain to the?
The increase amount of carbon dioxide in the blood stimulates is called the autonomic nervous system. This is what controls breathing.
What gas is increasing due to the destruction of the rain forest?
Both carbon dioxide and carbon monoxide. Carbon dioxide is caused by breathing of animals, and carbon monoxide is caused by burning. Trees and vegetation will absorb either. Carbon trioxide is unstable and does not exist outside of laboratories.
Is carbon dioxide a fat?
No, it's a gas. When you breathe out, you're breathing out carbon dioxide.
What are some health and environmental hazards of carbon dioxide?
There are no health hazards from breathing carbon dioxide in the atmosphere, but breathing pure carbon dioxide will kill you. The environmental hazard from carbon dioxide is that it is one of the greenhouse gases that is causing global warming.
What happens if there is an increase in carbon dioxide in the blood?
Water with dissolved carbon dioxide is acidic.
The breathing center in the brain is most sensitive to the?
levels of carbon dioxide in the blood. When carbon dioxide levels rise, the breathing center stimulates the muscles of respiration to increase breathing rate and depth. This helps to eliminate excess carbon dioxide and restore a balance in blood gas levels.
